[Oculo-oscillodynamography findings in glaucoma without hypertension]

Oculo-oscillodynamography after Ulrich was performed in 27 patients suffering from glaucoma without hypertension (so-called low-tension glaucoma). Patients who had severe systemic disease or were receiving systemic medication which might influence IOP, and patients with narrow angle and an IOP higher than 22 mm Hg were excluded. In 85% of the patients a severe decrease in systolic ciliary perfusion pressure was found, whereas the systolic retinal and diastolic ocular perfusion pressures were significantly lower in almost 30% of the cases. Glaucoma without hypertension appears to be caused by the vascular change at the disk.
